The clarity of the web of the carding machine directly affects the quality of the product. Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame.
During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process.
The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). Commonly referred to as superior analysis, web, primary web and secondary web, it refers to the clarity of the card web. Poor clarity and many cloud points will seriously affect the quality of the finished product, such as low spinning strength, uneven drying, more white cloth, and more bamboo yarn.
(1) Due to the poor carding degree, the fiber bundles form a disorderly arrangement, and the fiber distribution in the sliver section varies greatly. The drafting of each process can cause irregular fiber movement and uneven yarn thickness, which aggravates the uneven weight and evenness of the yarn. (2) The destruction of the twisting effect reduces the strength of the yarn, and the fabric defects affect the coarse details.
Because the card is not clear in the cotton mesh, the separation of the sheath monofilaments describes the difference in confusion and is arranged in the strip, with large twist bumps, resulting in uneven thickness uniformity, which not only affects the strength of the yarn, but also causes rough details in the appearance of cloth and white star white point. (3) The cotton web is clear, indicating that the carding machine has a good carding effect, and the fibers are straight and straight. In the process of twisting technology, the flat fibers are bent and twisted differently around the Chinese product design axis, forming a spiral line that is intertwined with each other, increasing the cohesion and friction force between enterprises, thus increasing the Increase the strength of the yarn.
The clarity of the cotton web is good. In each processing and production process, the generation of neps is small, the number of knots in the yarn is small, the white spot on the cloth surface is small, the appearance is good, and the dyeing and color difference are also small. The quality of the product in the steel cleaning process is good or bad, looks clear or wool, the best test criteria. Front-line managers, from a certain equipment, process, operation and temperature control, take measures to strengthen management.
